  • Fish
Universal entry(ies)
CONT

Pilot fish,(Naucrates ductor), widely distributed marine fish of the family Carangidae(order Perciformes). Members of the species are found in the open sea throughout warm and tropical waters.... The pilot fish is elongated and has a forked tail, a lengthwise keel on each side of the tail base, and a low first dorsal fin. It grows to a length of about 60 cm(2 feet) but is usually about 35 cm long. It is distinctively marked with five to seven vertical, dark bands on a bluish body. The pilot fish is carnivorous and follows sharks and ships apparently to feed on parasites and leftover scraps of food.

Subject field(s)
  • Biological Sciences
CONT

The disk-type centrifuge consists of a stack of thin disks in the shape of cones. The sedimentation takes place in the radial direction in the space between adjacent cones.... Feed enters at the center line of the rotating bowl and is accelerated by fins or channels at the bottom of the disk stack assembly before it is introduced into the bowl proper.... The heavy liquid separates quickly and settles to the bowl wall. Light liquid with some of the heavy liquid entrained as small drops enters the outside of the disk stack and flows up the sloped surfaces to the central portion of the disks. The entrained drops of heavy liquor are separated in the shallow layers between the disks and settle back to the bowl wall. Any solids contained in the feed are also settled to the bowl wall.... The bowl used with these machines contains a central stack of coned discs which ensure an almost constant length of flowpath, and the deposition of solids at the bowl wall produces only a minor reduction in the flowpath.

French

Domaine(s)
  • Sciences biologiques
CONT

Parmi les centrifugeuses de décantation, on trouve les centrifugeuses à basse vitesse et celles à haute vitesse. Dans tous les cas, la partie essentielle de l'appareil est le bol, c'est-à-dire le rotor à paroi pleine. Les centrifugeuses à haute vitesse développent des champs centrifuges supérieurs à 5 000 g. Les appareils les plus courants sont les centrifugeuses à disques. L'intérieur du bol comporte un empilage d'une centaine de disques qui divisent le bol en fines couches entre lesquelles circule la suspension. Ces appareils ont souvent un bol percé d'orifices calibrés qui permettent une sortie en continu des solides décantés et d'une partie de la phase liquide lourde. Les centrifugeuses à disques constituent le matériel de séparation le plus compact que l'on puisse trouver : une machine qui débite 200 m³/h occupe un espace au sol inférieur à 4 m².

  • Spacecraft
DEF

[An antenna] equipped with distributed transmit/receive modules which provide distinct transmit and receive beams.

CONT

The most significant difference between RADARSAT-2 and RADARSAT-1 payload technology is that RADARSAT-2 uses a fully-active phased array antenna, rather than the passive slotted waveguide antenna used by RADARSAT-1. Fully-active phased arrays offer a number of very significant benefits over passive antenna, but they also add great complexity.... The phased array is made up of 512 individual radiating elements, organized into 16 columns(picture below shows a single column) along the 15-metre antenna length, each with 32 rows across the 1. 5-metre width. The phase shifters and amplitude control are built into the Transmit/Receive(T/R) modules, which feed the radiating elements. Each column has a computer that controls the 32 T/R module settings and these 16 computers are all linked to another computer(in the spacecraft bus) that orchestrates the overall antenna behaviour.

OBS

active array antenna: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).

Subject field(s)
  • Atmospheric Physics
CONT

There are at least three distinct types of cold pool : 1. Large(in areal extent), slow-moving vortices at latitudes poleward of roughly 50deg N & S. They are often over, or immediately downwind of the source regions of polar or arctic air masses, in such areas as the Canadian Arctic or Siberian Russia.... 2. Once cold air from the source region as detailed in(1.) above is caught up in the circulation of mid-latitude depressions, the characteristics of the air mass are altered. Warming from below(over relatively warmer sea surfaces for example), leads to instability developing, and with an accompanying injection of moisture(after a reasonable length of passage over the sea), cloudy convection(showers, thunderstorms) is triggered. Cold pools in these situations are often maxima of such activity, with surface charts showing west or northwesterly airflow, often with cyclonically curved isobars. The cold pool will move in the general synoptic flow, and will eventually warm out(disappear) due to sensible & latent heat exchanges within the environment of the cold pool. However,... sometimes the cold pool will transform into a slow-moving, longer-lasting entity, particularly if the feed of ex-polar air on its western flank is maintained-this occurs in highly meridional situations. 3. A pool of cold air can also become ’detached’ at lower latitudes...

En 1992, deux auteurs anglais, Price et Vaughan, publièrent une étude statistique des gouttes froides, en séparant 3 types : les gouttes froides de type arctique, de type polaire et de type subtropicale, en fonction du courant-jet au voisinage duquel eut lieu le détachement stratosphérique. Ces auteurs montrèrent que les gouttes froides de type subtropical sont plus petite, et durent moins longtemps, que les gouttes froides qui se forment aux latitudes moyennes et polaires.

CONT

CONT

Aerofall Mill. The aerofall autogenous and semi-autogenous air swept mills are additional solutions for dry grinding. These mills are typically very large in diameter and very short in length achieving high throughput. The material is lifted to great heights using lifter bars and dropped with forceful impact onto itself in the mill. The mill system would include separators and cyclones downstream from the mill to return rejected material to the mill, if needed. The aerofall mill is good for grinding abrasive materials with high moisture content and large feed size.

CONT

Quarried material is taken by conveyor or trucks to the processing plant where, if it is in rock form, it will be crushed to ensure that it is of a suitable size to pass by conveyor to the stockpile. From the stockpile it is fed, again by conveyor and a controlled amount of water to a rotating aerofall mill, which contains heavy metal liners, which help tumble the rock onto itself, crushing through various screens, spiral classifiers and washing tanks to remove unwanted impurities.

Phalanger. Common name applied to marsupial mammals of the family Phalangeridae, found in Australia, Tasmania, the Solomon Islands, the Moluccas, and Celebes. Members of the family have been introduced into New Zealand. Head and body length ranges from 16 to 65 cm(6 to 26 in), tail length from 17 to 61 cm(7 to 24 in). All the members of the family have five toes on each foot; each digit, except for the opposable innermost toe of the hind foot, has a large claw. Phalangers are nocturnal, arboreal animals that feed chiefly on fruit and leaves. Some species also feed on nectar, insects, and, occasionally, small birds.

Length measuring is accomplished by means of a steel measuring wheel, which is located in the centre of the harvester head between the feed rollers, and is applied under constant hydraulic pressure against the tree as it is fed through the head by the feed rollers. This measuring wheel is connected directly to a circular optical encoder disc located in the pulse emitter unit which, in turn, is wired to the computer. Figure 2 shows the location of these components on the harvester head.

Subject field(s)
  • Radio Transmission and Reception
OBS

The Rohde & Schwarz active rod antenna HE010 allows a sensitivity which is near the theoretical maximum even for small atmospheric-noise figures. The antenna, only 1 m in length, operates in the frequency range 10 KHz to 80 MHz, is largely immune to noise signals, has two isolated outputs and is therefore able to feed two receiving paths in wideband operation without reducing the sensitivity. The study mechanical construction of glassfibre-reinforced polyester and the wide voltage range from 18 to 35 V make the rod antenna particularly suitable for mobile use.

French

Domaine(s)
  • Émission et réception radio
OBS

L'antenne-tige active HE010 de Rohde & Schwarz est d'une sensibilité proche du maximum théorique, même à de faibles niveaux du bruit atmosphérique. Longue de 1 m seulement, cette antenne fonctionne dans la bande 10 KHz - 80 MHz, d'une grande immunité aux signaux de bruit, elle a deux sorties distinctes et se prête donc à la réception de deux catégories d'émission à large bande, sans réduction de la sensibilité. La robustesse de la construction mécanique (polyester renforcé de fibre de verre) et l'étendue de la gamme de tension (de 18 à 35 V) font de cette antenne un dispositif particulièrement approprié au service mobile.
